Just had the bushes replaced on the Jayco 24 ft, why you ask? Preventitive maintainence says I. I got a quote from my local dealer, 10-12 hours @ $77 per hour plus parts Last year whilst in Walkamin FNQ a young gent fitted my own wheel bearings for me, complete with seals etc for $90. Today he came to us in Cairns, checked, repacked bearings and fitted new seals to the four wheels, checked and adjusted brakes. Replaced all bushes in suspension, greased new main rocker bush. $298, now thats a good deal.
